A nozzle for dispensing fluid includes a nozzle stem that controls the flow of fluid out of a dispensing end of the nozzle. The nozzle stem includes an overmolded stem tip on a reduced diameter portion of the nozzle stem. The overmolded stem tip is formed from a compliant material and includes a sealing portion and a tip cone extending from the sealing portion.

An auxiliary or additive fluid for associated use with the primary diesel or related fuel, for application for reduction of exhaust pollution, and for motor or truck vehicle, or the like, includes the nozzle, the nozzle having its spout extending from its forward end, the spout having an outer sleeve, an inner sleeve through which the fluid flows during dispensing, a lower sleeve capable of shifting within the outer sleeve, and integrated with a safety valve sleeve, and biased axially inwardly of the spout when it is inserted into the fluid intake pipe of a vehicle intake for a fluid tank. A primary safety valve extends through the lower spout sleeve, and the integral safety valve sleeve is maintained in a fixed position, and normally is sealed into closure within the lower end of the lower spout sleeve. But, when the lower spout sleeve is forced axially inwardly, it unseats the safety valve from its sealing therewith, to open the spout for the dispensing of the fuel when the nozzle is actuated to allow fluid flow. In addition, a flow path for air that is normally closed by a check valve, is likewise opened, to allow for the passage of air to maintain the inoperativeness of the automatic shut-off, until such time as the fluid flow closes off the lower end said passage, initiating the automatic shut-off of the fluid dispensing nozzle, when the intake of air is blocked.

A testing or filling adapter (1) for a container to be filled with fluid, composed of a body (10), an attachment module (3), and a coupling system (30) having a coupled position, in which a sealed connection is established between the body and the attachment module, and an uncoupled position. The body includes a feed module (2) that comprises a plurality of conduits that include at least one fluid conduit (221) and is equipped with a safety valve (5) that can be moved between an open configuration and a closed configuration and is connected to an element mirror (51) having a first configuration in which the safety valve is in the open configuration and a second configuration in which the safety valve is in the closed configuration. The filling adapter further comprises a safety device (6) that cooperates with the coupling system, with it being possible to move said safety device between a locked position, in which the safety device locks the coupling system in the coupled position, and an unlocked position, in which the safety device enables the coupling system to be moved into the uncoupled position. The safety device cooperates with the mirror element so as to enable the mirror element to be in its first configuration when the safety device is in the locked position, and to force the mirror element to be in its second configuration when the safety device is moved from its locked position to its unlocked position.

A handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter and to modify the functionality of buttons that control scrolling on the display. The control circuitry inverts the orientation of the visual output based on a command provided to the control circuitry by a user or by a position sensor.

Apparatuses and methods of operating the same are described. An apparatus may include a lower compartment, a baffle, and an upper compartment. The lower compartment may form a lower cavity to hold a liquid. The baffle may include a channel connecting the lower compartment to an upper compartment, where the channel provides a first passageway for liquid to pass between the lower compartment and the upper compartment. The baffle may also include a baffle passage defining an opening through a middle section of the liquid container between the lower compartment and the upper compartment. The upper compartment may form an upper cavity to hold the liquid.
